scilab interface with C

[Samy]

Hello,
I am a French student (at ENSTA ParisTech) and I am currently working with prof. Chris Rogers at Cambridge University.
I would like to know if an interface exists in order to use a package computed in C in Scilab. Actually I would like to interface the qhull package (which determines the convex hull of a set of points, among other things), which is programmed in C, to use it with Scilab.

I know that it is possible to interface functions in C but as there are many functions in this package I would like to know if there is a better way to use the package in Scilab than to interface all the functions one by one.

Thanks for considering my request.

Regards.
Samy Hocini.
